I know that to play in third person, you need to use sv_cheats 1, but if I prove that I'm not using noclip/god, would it be accepted?

why would you do that though

Because it would be funny. Now answer my question

No, it's not allowed.

Нет, это не примут, любые команды которые доступны только с sv_cheats 1 запрещенны
